SILQ-DOOR MOUNTING.

Patented Oct. 22, 1918.

Application led April 23, 1917. Serial No. 163,888.

To all cli/'tom t may concern:

Be it known that I, ROY Lorriurivn,y a citizen of the United States,residing at Wortlr ington, in the county of Greene and State of Indiana,have invented certain new and useful Improvements in Silo-DoorMountings, of which the following is a specication, reference being hadtherein to the :accompanying drawing. Y

This invention relates to certain new and useful improvements in silodoor mountings, the object being to provide a door mounting which is soconstructed that the door is adjustably supported in a rigid manner soas to prevent the same from sagging. Y

Another object of my invention is to provide a door mounting in whichthe door is pivotally and adjustably supported on piv oted arms in orderto enable the same to be adjusted so as to obtain an accurate fitwhen inclosed position within the door frame.

Another object of my invention is to provide a novel form of supportingmembers adapted to receive hangers carried by the door in such a mannerthat the door is free to swing on the supports and the supports on thepivoted arms in order to obtain a universal movement.

Another and further object of my invention is to provide a door mountingcomposed of a pair of pivoted arms connected together by braces havingcurved ends in order to enable the pivotally mounted door carried by thefree ends of said arms to be swung into the silo against the inner faceof. the wall thereof so as not to obstruct the filling of the silo.

Other and further objects and advantages of the invention will behereinafter set forth and the novel features thereof dened by the n Inthe drawing I have shown my improved construction of door mountingapplied to a silo and door formed of plastic material in which lindicates the wall of the silo, 2 a series of superposed door frameswhich are Aprovided with rabbeted edges as shown at 3 into which isadapted to fit the rabbeted edges 4c of a plastic door 5, it of course,being understood that a door is provided for each door frame and eachframe and door is constructed exactly like each other frame and door.

Embedded within the walls of one of the side pintles of the door frameis a vertically disposed reinforcing element 6 in the form of a flat barhaving angled apertured ends 7 projecting out beyond the face of thedoor frame forming horizontally disposed bearings on which are mountedthe apertured pivot portions 7 of arms 8, said pivot portions being heldon the bearings 7 of the elements 6 by a vertically disposed pintle 9.The arms 8 are provided with curved portions 10, the pivot portions 7being formed by twisting the ends of the strips from which the arms areformed, and these arms are connected together by braces 11 in order toproduce a substantial frame, the arms forming rounds so as to provide aladder for the silo or other structure.

The free ends of the arms 8 are twisted to provide horizontally disposedbearing portions 12 which are provided with apertures in which arepivotally mounted the sprockets 13 of supports 14 adapted to turn on thebearings 12 as will be hereinafter fully described.

The supports 14 are bifurcated as shown at 15 adapted to receive theU-shaped hangers 16 carried by the door 5, said hangers being providedwith right angled ends 17 adapted to be embedded within the plastic doorwhile being molded so as to securely anchor the hangers within the door.One of the furcations of the bifurcated support 14 is provided with athreaded bore 18 adapted to receive a set screw 19 which is pointed andis provided with a concaved end 2O adapted to engage the U-shaped hanger16 so as to lock the hanger in adjusted position within the support 14.

The hangers 16 are preferably formed of wrought iron in order to enablethe same to -be bent slightly in order to obtain a slight adjustment,and by adjusting these hangers Within the pivotally mounted supportscarried by the arms, the doors can be adjusted in respect to the doorframes so as to obtain an accurate lit when in closed position. Thecurved portions 10 of the arms alloiv the door to be swung into andagainst the inner face of the silo.

rl`he doors are held in closed position by locking` bars 21 pivotallymounted on the doors.

From the foregoing- Vdescription it will be seen that I have provided asilo door mounting in which a :trame formed of a pair of pivotallymounted arms connected together by, braces is pivotally mounted onbearings carried by the door frame, and is providedY With spacedbearings on which are pivotally mounted supports in which are adjustablymounted hangers carried by the door, Whereby I am able to support a doorWeighing from seventy-live to one hundred and twenty-five pounds in arigid manner so that the door when in closed position will titaccurately Within the door frame in order to form a tight closure whichis essential in a silo door.

I claim:

l. The combination with a structure having a door frame and a pair oizarms pivotally carried by said door iframe, vertical supports pivotallymounted upon said arms, a door having substantially 'Ll-shaped hangersslidably mounted in said supports, and means for locking' said hangersin adjusted position within said supports.

EZ. The combination with asilo having a door frame and a door therefor,of a reinforcing element embedded within the door frame having angledends 'forming bearings, arms pivotally mounted on said bearings, bracesconnecting said arms, said arms being provided ivith'bearings at theirfree ends, biit'un cated supports pivotally mountedv upon said bearings,U-shaped hangers carried by said door mounted Within said supports, andmeans for locking` said hangers in adjusted position within saidsupports.

3. The combination with a silo having a door frame and a door therefor,of a bar embedded Within the door frame having an gled apertured endsforming bearings, arms provided With apertured pivot portions mountedupon said bearings, a pintle pin eX- tending` through said bearings andpivot portion, means connecting said arms, said arms having horizontallydisposed apertured bearings at their free ends, supports provided withpivots mounted in the apertured bearings of said armsJ U-shaped hangerscarried by said door, laterally adjustably mounted Within said supports,and set screws carried bymsaid supports engaging said hangers forlocking said hangers in adjusted position Within said supports.

4l. The combination with a silo having' a door frame and a doortherefor, formed oli plastic material, of a pair of arms pivotallysupported by said door frame, braces connecting' said arms, said arms'being provided With horizontally disposed apertured bearings at theirfree ends, supports mounted on said bearings having pintles extend inginto the apertures thereof, said supports being provided With bifurcatedportions, hangers carried by the door mounted for lateral adjustmentWithin the bifurcated portions of. said supports, and set screws havingcup-shaped ends mounted in said supports engaging said hangers forholding said hangers in adjusted position Within said supports.

5. A silo door mounting comprising a pivotally mounted frame havingbearings at its free end, vertical supports `pivotally mounted on saidbearings, door hangers having horizontally disposed portions arrangedparallel with the face of the door slidably mounted Within said supportsfor lateral adjustment and means for locking said hangers in adjustedposition Within said supports.
